WebThe influence of acid concentration was greater than reaction time in this regard, which indicated that a higher oxalic acid concentration is required to efficiently hydrolyse hemicellulose from the PKC. Therefore, the optimum residence time and oxalic acid concentration were found to be 4 hs and 3% (v/v) oxalic acid, respectively. Sulfuric acid (American spelling and the preferred IUPAC name) or sulphuric acid (Commonwealth spelling), known in antiquity as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen, and hydrogen, with the molecular formula H2SO4.
